SASH HOLDER.

LOY B Q EQQL Specification of Letters Patent.

. d May 13.1913.

Application Pa t ented Nov. 18, 1913. Serial No. 767,278.

Be it known that 1, Jenn .i'lOL'lLHAN. a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful In'iprovei'nents in Faish-l'lolders, of which the following is a specification.

This invention relates to sash locks for windows, and particularly to sash holders for the type of windows wherein an upper and a lower sash guided in ways are slidable upwardly and downwardly for open inn and closing the window.

The principal objeet of my invention is to provide an improved window sash holder.

Another object is to provide means for positively maintaining the holder in locked state and prevent; releasing thereof from the exterior of the apartment when the window is partially left open for ventilation.

A further object is to provide means for setting the holder in inoperative state for allowing the window sashes to open freely.

In carrying out the invention, an inclined base is secured to the lower sash and a roller cooperating with said base is wedged thereagainst by pressure of the upper sash against the periphery of said roller, whereby movement of the sashes to open the window is automatically prevented. Said roller is mounted to rotate on a releasing lever which is slotted at its fulcrum to permit the roller to roll freely on said base. Actuating of said lever li'lis said roller temporarily to permit opening of the window. A tapped not is pivotally seeured to said lever and a screw threading therethrough i adapn able to be threaded agaiint a fixed projection or into a threaded opening therein. Threading the screw against said projretion positively maintains said roller in locked state, whereby tampering therewith from the exterior is pi'mented. and iii-endi g; said screw into said opening holds said roller lifted and positiiely maintains the lock in inoperative slate.

Other objects and advantages will hereinatter appear.

In the aerompartying drawings Figure 1v is a general side elevation of the window holder, showing its parts in the position when. locking the window sashes. Fig. 2 is a view similar to Fig. 1, and shows the pmrition of the parts when the holder is released for opening the window. Fig. 3 is a view similar to Fig. 2, and shows the holder set to be maintained in inoperative state and the window sashes free to open. Fig. 4 is a front elevation of the holder as seen when its parts are in the position shown in Fig.

The upper window sash 1 and the lower window sh 2 are suitably guided in ways and are (-oiinter-weighted in the well known manner, whereby they may be shifted upwardly and downwardly to open and close the window. The holder is fixed on top of the lower sash 2, opposite the side of the frame of sash l, by means of ears 3 depending from its base. 4 being: secured to sash 2 with wood screws 5 Said base comprises a rear wall (I, a wall 7 inclining downwardly from .wall 6 toward the sash 1, and side walls 8 at each side of said inclined wall and parallelly to each other. A roller 9, preferably provided with a rubber periphery l0, adaptable to roll upwardly and downwardly along the inclined wall 7, and is guided laterally by the side walls 8. Any atten'ipted movement to open either of said sashes, a downward increment of the upper sash or an upward movement of the lower sash. causes the roller 9 to be wedged between the inclined wall 7 and the side 1 of the sash, Fig. 1, whereby such relative movement. of the sashes is normally prevented.

The roller 9 is rotatably mounted to run on i: journal or bearing 11 which forms part, of a releasing lever 12 fnlcruined on a stud l3 fixed to the wall of easing 4, and said lever has a slot I l at its fulcrum whereby the roller 9 is permitted to roll in contact with every portion of the inclined wall 7 while being fittingly mounted on its' ournal ll.

Pressure upon the extremity 15 of lever 12 lifts the roller to the position shown in Fig. 2, which temporarily releases the roller and enables the window to be opened, by downward movement of the upper sash or upward movement of the lower sash, to any desired position. Upon releasing the pressure on said lever the roller 9 is restored to its normal position, Fig. 1, and automatically looks the sashes, which precludes further movement of either sash in a direction to open the window, although the upper sash is free to be moved upwardly and the lower sash downwardly to close the window.

When the windmv is opened partially at night to permit ventilation of the apartment, it is desired to prevent burglars from tamporing with the sash holder in order to open the window fully, who might press the lever 12 by reaching thereto with a rod or pull the roller 9 with a hook to render the holder inoperative. For this purpose a nut 16 is pivotally secured to the lever 12 adjacent its extremity 15, and a screw 17 threading therethrough is provided with a smooth round head 18 and a small lug 19 at its end. To prevent tampering with the lock to render it inoperative said screw is threaded downwardly to the position shown by the dot and dash lines, Fig. l, and its lug 19 thereby caused to enter an openin 20 provided in a projection. 21 extending mm the casing 4, whereby actuating of said lever is prevented and the roller is maintained in locked state. Threading the screw 17 back to the position shown restores the holder to normal action.

If it is desired to maintain the holde set in inoperative state to enable opening 0 the window freely, without requiring actuating of the releasinglever-l2, for such purpose as cleanin the window-panes, said lever is swung to t. e position shown in Fig. 3 to release the roller 9 and the screw 17 is caused to thread within a tapped 0 ening 9-2 provided in projection Ell, whic permanently holds said lever and roller in inoperative po- ,sition. Threading back the, screw 17 to the position shown in Fig. 1 restores the holder to operative state.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim 2- 1. In a Window sash holder, the combination with a base on one of the sashes, and a roller adaptable to cooperate with said base to prevent relative movement of the sashes, of a lever for releasing said roller, {1 nut pivoted to said lever, a screw threading through said nut, a fixed member having an opening and a tapped opening, said screw ada table to engage said opening to maintain sai lever to hold the roller in locked position, and said screw adaptable to thread Within said tapped. opening to maintain said lever to hold the roller in inogiierative position.
